Definitions

• the interfiber cohesion of filament yarns is improved by applying a fiber-treating agent to a filament yarn and aging, said fiber-treating agent consisting of (a) a high-molecular-weight surfactant (A) composed of a copolymer of an anhydride of an unsaturated dibasic acid with a vinyl compound copolymerizable therewith, in which a part of the acid groups are amidated by an aliphatic amine containing at least one aliphatic alkyl group having 1 to 22 carbon atoms and the remaining acid groups are converted to salts of an alkali metal, a lower amine, an alkanol amine or ammonia, and (b) at least one compound selected from the compounds expressed by the following general formulas (l) to (4):
• R is an alkyl or alkenyl group having 8 to 18 carbon atoms or a residue of a condensate of 1 mole of a higher alcohol having 8 to 18 carbon atoms with 1 to 10 moles of ethylene oxide
• X stands for a hydrogen ion, a metal ion, a residue of a polyethylene glycol (the mole number of ethylene oxide being 1 to 5), an ammonium ion or an organic group-substituted ammonium ion
• m and 11 stand for an integer of 1 to 2 with the proviso that the sum of m and n is 3;
• interfiber cohesive property means the interfiber cohesive property required at the filament-manufacturing steps and does not mean the interfiber cohesive property required at the staplemanufacturing (spinning) steps.
• Natural pastes such as wheat starch, sweet potato starch, potato starch, sodium alginate and laver, and synthetic pastes such as carboxymethyl cellulose, polyvinyl alcohol, polyacrylic acid, polyvinyl acetate and polymethyl acrylate have been mainly used as agents for improving interfiber cohesion of filament yarns.
• these fiber treating agents heretofore used have a defect that they reduce the fiber to metal lubrication. Therefore, they are disadvantageous in that they must be used, in general, in combination with lubricants'called sizing oils. They are also defective in that it is difficult to accomplish scouring of fibers treated with such agents in a short period of time.

• the ratio of the amidated carboxylic acid groups may be optionally selected so as to vary the hydrophilichydrophobic balance of the high-molecular-weight surpressure to obtain a solid having a molecular weight of about 2000 and a degree of saponification of 282. Then, 200 g (1 equivalent) of the solid was collected and dissolved in 200 g of acetone, and 39.4 g (0.2 mole) of lauryl amine was added dropwise to the solution at 57 58C over a period of 2 hours.

• lt is possible that the ratio of the unsaturated dibasic anhydride to the vinyl compound is adjusted within a range of from 5:l to 1:5, but it is preferred that the said ratio is within a range of from 2:1 to 1:2. The optimum ratio is 1:1.
